But Tim Chapman's lawyer insists his client spilled juice on himself and was just changing clothes Thursday night.

The guard told Chapman to put on his clothes and get out of the truck, police said. After dressing, Chapman started his truck and drove over a sidewalk, nearly hitting the guard, then drove off, police said.

The guard told police that he recognized Chapman from Duane Chapman's show "Dog the Bounty Hunter" and that he was performing an unspecified lewd act. Duane Chapman and Tim Chapman are not related.

Tim Chapman's attorney, Brook Hart, said it was all a misunderstanding.

"It was simply a man who wet his pants with orange juice inadvertently and was changing them, doing nothing wrong at all and believing he had sufficient privacy to do it," Hart said.

Police said they were investigating whether to charge Chapman, 42.

The A&E television network put the show on hold indefinitely in November after the release of a private phone conversation in which Duane Chapman repeatedly used a racial slur to describe his son's girlfriend. He has apologized repeatedly.
